Be it known that I, NATHAN M. LOWER, a citizen of the United States, and resident of Schenectady, county of Schenectady, and State of New York, have invented certain vnew and useful Improvements in Locomotive-Tenders, of which the following is a specification, and which are illustrated 1n the accompanying drawings, forming a part thereof.

The invention relates to locomotive tenders in which there is rovided a fuel bin; its object being to provide improved means for advancing the fuel to the shoveling platform, where it will be within easy reach of the fireman. It consists i n providing such tender with one or more screw conveyers located immediately above the lfuel-supporting walls of the bin, and with power means for operating such screw or screws.

1n the accompanying drawings- Figure l'is a detail plan view of the fuel bin of a tender;

Fig. 2 is a detail vertical longitudinal section thereof, partly in elevation; and

. Figs. 3 and 4 are details of the driving gear for o erating the conveyer screws.

The ten er shown is of that type in which the fuelbin is provided with an inclined slope sheet at its rearward end, and is supplemented by a fuel-carrying deck back of the bin roper, but the invention is applicable to ten ers provided with bins of different coniguration and without a supplemental deck.

The side walls of the fuel bin are represented at 10, 11, its bottom is shown at 12, and its slope sheet at 13. At 14 there is shown a fuel deck extending backwardly from the upper end ofthe slope sheet and provided with a vertical back wall 15. The fuel is supported by the floor 12, the slope sheet 13, and the deckv Hoor 14. Mounted upon each of these supporting ioors are screw conveyers 16, 17, 18; as illustrated in Fig. 1 four of each of these conveyers being shown. As many may be provided as may be deemed advisable. These conveyers are of the usual form, each comprising a shaft on which is mounted a spiral flange. The shaft of each conveyer is journaled in one or more brackets rising from the fuel-supporting wall with which the conveyer is associated, and for convenience in driving the Specication of Letters Eatent.

conveyers of each set may be connected/by means of universal Joints or by means of simple gearing.

As shown, the rearward end of the shaft of the conveyer 18 is journaled in a bracket 19 rising from a plate 20 which may be secured to the iioor 14 of the deck by any suit-f able means, and preferably extends the entire length of the conveyer to take the wear incident to the forward movement of the sheet and extending backwardly the entire length of the conveyer. The forward end of the shaft of the conveyer 16 is journaledy in a bracket 26, rising from a plate 27 suitably secured to the floor of the fuel bin and extending backwardly the entire ylength of the conveyer. The rearward end of the shaft of the conveyer 16 is preferably secured to the forward end of the shaft of the conveyer 17 by a universal joint 28.

The rearward end of the shaft of the conveyer 17 and the forward end of the shaft of the conveyer 18 are provided with bevel gears 29, 30, which mesh with a similar gear 3l xed upon a shaft 32 extending Atransversely across the tender, and to Awhich power is applied for driving the several conveyers. Inasmuch as the direction of rotation of the conveyer 18 is the reverse of that of the conveyers 16 and 17, its spiral langeis given a reverse direction relatively thereto. n,

A suitable motor is provided for driving the conveyers. Such a motor is conventionally shown at 33, andl as being located at the forward end of the tender, its shaft 34 extending backwardly and being provided with a bevel gear 35 which meshes with a `pair of similar gears 36, 37, loosely mounted lso wardly and in convenient reach of the {ireman, this rod actuating a shipper yoke 40 in engxagcment with the clutch.

here a plurality of sets of conveyers is employed, as shown, all are driven by means of the single shaft 32.

In order to protect the gearing from the fuel the brackets 21 and 22 take the form of a housing, including a cover plate 41.

When the tender is first loaded with fuel, the conveyer or conveyers will be entirely submerged therein and by theiraction will advance the lower fuel stratum, the upper portion of the load settling down as the ad- Vance movement is continued. The conveyers are preferably suticiently close together so that substantially all of the fuel will be carried forward to the shoveling platform. Should any clogging occur the direction of rotation of the conveyers may be reversed by shifting the clutch. The conveyers may be driven continuously, or may be operated intermittently ,either by the motor or clutch control. 'Y

of construction is shown and described, various changes in detail may be introduced without departing from the scope of the invention.
